Description

Pipe cleaning device {PIPE CLEANING APPARATUS}

The present invention relates to a cleaning device for pipes.

In general, the Excel pipe used for the purpose of transporting drainage or water supply, water supply and sewage or sewage water has a problem of contamination of water by rusting or depositing deposits on the inner circumferential surface of the pipe during long-term use.

In addition, metal components or soil contained in water are attached to the inner circumferential surface of the pipe, which makes the flow of the fluid difficult, decays over a long period of time and causes environmental pollution. There was a problem that got worse.

In particular, if the removal of suspended matter deposited in the pipe is neglected, the sewage flow in the pipe will not be smooth, and the sewage inside the pipe will overflow to the ground due to the poor flow of sewage during heavy rains in summer, etc. is becoming a factor in

Therefore, it is necessary to periodically clean the inside of the pipe, and for this purpose, an entrance is made on one side of the pipe for the operator to enter and exit, and the operator enters with a separate brush or, in the case of a pipe without an entrance, a buried pipe After exposing the pipe, one side of the connected pipe is separated, and the operator picks up a brush with that part and inserts it into the inner space of the pipe for cleaning.

However, the conventional pipe cleaning work is very cumbersome, requires a lot of manpower, and when there is no entrance, the work cost increases due to time and labor costs due to the need to separate and assemble the pipe, which is uneconomical.

In order to solve this problem, Korean Patent Registration No. 0751385 "Pneumatic cleaning screw using pneumatic" has been proposed.

Domestic Patent Registration No. 0751385, "Pneumatic cleaning screw using pneumatic", attaches a brush with a large physical action to the screw and then injects compressed air into the pipe to apply rotational force to the screw. that it can be removed.

Domestic Patent Registration No. 0751385, "Pneumatic cleaning screw using pneumatic pressure" has an advantage compared to the above devices in that it directly rubs against the inner wall scale using a brush as a cleaning material. In the case of supply, there is a problem in that energy loss occurs significantly, and rotational force and propulsion force of the desired degree do not occur.

Domestic Patent Registration No. 0751385 “Pneumatic cleaning screw” uses a brush as a cleaning material and rotates the screw only with the power of compressed air to remove scale on the inner peripheral surface of the pipe with the brush, so the cleaning efficiency is lowered and the cleaning efficiency of the pipe is reduced. There was a limit in removing foreign substances such as scale or sludge on the inner circumferential surface.

As the body housing part 100 moves in the longitudinal direction of the pipe 10, the brush member 330 rotates in the circumferential direction of the pipe 10 and rotates in the longitudinal direction of the pipe 10 to efficiently remove sludge, , the auxiliary washing water spraying unit 800 removes foreign substances such as sludge remaining on the inner circumferential surface of the pipe 10 by re-spraying the washing water to the portion washed with the brush member 330 .

In addition, as the body housing part 100 moves in the longitudinal direction of the pipe 10 , the rotating suction duct part 1000 and the suction duct part rotate integrally with the brush part 300 , while the washing water used for washing and the pipe 10 ) by sucking foreign substances such as sludge removed by the brush member 330 from the inside and discharging it to the outside of the pipe 10 through the suction hose member 900 to remove it.

The present invention can reduce the cleaning time of the pipe 10 by efficiently removing the sludge attached to the inner circumferential surface of the pipe 10 with a brush while spraying high-pressure water, and improve the convenience of the cleaning operation.

The present invention can efficiently remove the sludge attached to the pipes 10 having different diameters, so that the pipes 10 of various diameters can be efficiently washed.

In the present invention, the washing water used for washing and the sludge washed and removed can be sucked and removed from the pipe 10, so that the washing efficiency is prevented from being lowered by the sludge removed and the washing water used during washing, and the pipe is more efficiently (10) It is possible to wash the inside and minimize the time required for the cleaning operation.

It should be noted that the present invention is not limited to the above-described embodiment, and can be implemented with various modifications without departing from the gist of the present invention, which is included in the configuration of the present invention.
